Bands get formed for all kinds of reasons, but those who started Surfer Blood did it to play music as much as possible—to record an album and tour nonstop. They made a name for themselves, locally at least, during CMJ Music Marathon 2009, and then even more so with the arrival of their well-received debut, Astro Coast (stream it below), in 2010. The band “has become a standard bearer of the wi-fi lo-fi era in short order,” proclaimed PopMatters. “The highest praise you can give an album like Astro Coast is that it sounds like something completely familiar that you haven’t heard before.” Surfer Blood (above, doing “Six Flags in F or G” for KEXP FM) have remained busy touring and recording ever since. And although group has dealt with death and lineup changes, they continue to persevere. Their fourth studio album, Snowdonia (stream it below), came out this past February. “There’s a clear sense of melancholy and yearning, but there’s also optimism spilling out from the edges,” according to the Line of Best Fit. “Grief and hardship have changed Surfer Blood, there’s no denying that. But they deserve praise for making a record that still has its own joie de vivre and doesn’t completely overhaul the alphabet that has made the band a success in the first place.” See them on Thursday night at Music Hall of Williamsburg. Brooklyn trio Lazyeyes open the show.
